The estimation of the parameter population of greasyback shrimp (Metapenaeus ensis) inBangka Strait was an important information as a fisheries management policy for sustainable shrimp fisheries. The aims of this research was to assess population parameters and exploitation rate of greasyback shrimp in Bangka Strait based on biological data (size distribution, sex ratio and gonad maturity). Biological datacollected from February – November 2014 at landing base inBanyuasin. The Method to estimate population dynamic was analyzed by using FiSAT II, the results showed that the average of greasyback shrimp that was captured had not spawned yet (Lc<Lm). The spawning seasonoccurred in July.Carapace asymptotic length (CL∞) of male shrimp was 45,0 mm and the female was 49,5 mm. The growth parameter of greasybackshrimp was 1,40/year for male and 1,45/year for female.Total mortality rate (Z), natural mortality rate (M) and fishing mortality rate (F) for male shrimp were 4,82/year, 2,06/year and 2,76/year.Total mortality rate (Z), natural mortality rate (M) and fishing mortality rate (F) for female shrimp were 3,98/year, 2,01/year and 1,97/year. Exploitation rate of greasyback shrimp inBangka Strait were 0,57 for male and 0,49 for female. The exploitation of male greasyback shrimp was fully exploited so that it needed careful regulation. Therefore, the regulation about mesh size, amount of fishing fleet, periodicity of fishing were needed for sustainable shrimp fisheries.
